Significant Accounting Policies [Abstract]

Nature Of Operations

Nature of Operations—Umpqua Holdings Corporation (the "Company") is a financial holding company headquartered in Portland, Oregon, that is engaged primarily in the business of commercial and retail banking and the delivery of retail brokerage services. The Company provides a wide range of banking, asset management, mortgage banking and other financial services to corporate, institutional and individual customers through its wholly-owned banking subsidiary Umpqua Bank (the "Bank"). The Company engages in the retail brokerage business through its wholly-owned subsidiary Umpqua Investments, Inc. ("Umpqua Investments"). The Company and its subsidiaries are subject to regulation by certain federal and state agencies and undergo periodic examination by these regulatory agencies.

Basis Of Financial Statement Presentation

Basis of Financial Statement Presentation—The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States and with prevailing practices within the banking and securities industries. In preparing such financial statements, management is required to make certain estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the balance sheet and the reported amounts of revenues and expenses for the reporting period. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan and lease losses, the valuation of mortgage servicing rights, the fair value of junior subordinated debentures, the valuation of covered loans and the FDIC indemnification asset, and the valuation of goodwill and other intangible assets.

Consolidation

Consolidation—The accompanying consolidated financial statements include the accounts of the Company, the Bank and Umpqua Investments. All significant intercompany balances and transactions have been eliminated in consolidation. As of December 31, 2011, the Company had 14 wholly-owned trusts ("Trusts") that were formed to issue trust preferred securities and related common securities of the Trusts. The Company has not consolidated the accounts of the Trusts in its consolidated financial statements in accordance with Financial Accounting Standards Board Accounting Standards Codification ("FASB") ASC 810, Consolidation ("ASC 810"). As a result, the junior subordinated debentures issued by the Company to the Trusts are reflected on the Company's consolidated balance sheet as junior subordinated debentures.

Subsequent Events

Subsequent events—The Company has evaluated events and transactions subsequent to December 31, 2011 for potential recognition or disclosure.

Cash And Cash Equivalents

Cash and Cash Equivalents—Cash and cash equivalents include cash and due from banks, and temporary investments which are federal funds sold and interest bearing balances due from other banks. Cash and cash equivalents generally have a maturity of 90 days or less at the time of purchase.

Trading Account Securities

Trading Account Securities—Debt and equity securities held for resale are classified as trading account securities and reported at fair value. Realized and unrealized gains or losses are recorded in non-interest income.

Investment Securities

Investment Securities—Debt securities are classified as held to maturity if the Company has both the intent and ability to hold those securities to maturity regardless of changes in market conditions, liquidity needs or changes in general economic conditions. These securities are carried at cost adjusted for amortization of premium and accretion of discount, computed by the effective interest method over their contractual lives.

Securities are classified as available for sale if the Company intends and has the ability to hold those securities for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of assets and liabilities, liquidity needs, regulatory capital considerations and other similar factors. Securities available for sale are carried at fair value. Unrealized holding gains or losses are included in other comprehensive income as a separate component of shareholders' equity, net of tax. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. Premiums and discounts are amortized or accreted over the life of the related investment security as an adjustment to yield using the effective interest method. Dividend and interest income are recognized when earned.

Prior to the second quarter of 2009, the Company would assess an other-than-temporary impairment ("OTTI") or permanent impairment based on the nature of the decline and whether the Company has the ability and intent to hold the investments until a market price recovery. If the Company determined a security to be other-than-temporarily or permanently impaired, the full amount of impairment would be recognized through earnings in its entirety. New guidance related to the recognition and presentation of OTTI of debt securities became effective in the second quarter of 2009. Rather than asserting whether a Company has the ability and intent to hold an investment until a market price recovery, a Company must consider whether it intends to sell a security or if it is likely that they would be required to sell the security before recovery of the amortized cost basis of the investment, which may be maturity. For debt securities, if we intend to sell the security or it is likely that we will be required to sell the security before recovering its cost basis, the entire impairment loss would be recognized in earnings as an OTTI. If we do not intend to sell the security and it is not likely that we will be required to sell the security but we do not expect to recover the entire amortized cost basis of the security, only the portion of the impairment loss representing credit losses would be recognized in earnings. The credit loss on a security is measured as the difference between the amortized cost basis and the present value of the cash flows expected to be collected. Projected cash flows are discounted by the original or current effective interest rate depending on the nature of the security being measured for potential OTTI. The remaining impairment related to all other factors, the difference between the present value of the cash flows expected to be collected and fair value, is recognized as a charge to other comprehensive income ("OCI"). Impairment losses related to all other factors are presented as separate categories within OCI. For investment securities held to maturity, this amount is accreted over the remaining life of the debt security prospectively based on the amount and timing of future estimated cash flows. The accretion of the amount recorded in OCI increases the carrying value of the investment and does not affect earnings. If there is an indication of additional credit losses the security is re-evaluated according to the procedures described above. OTTI losses totaling $359,000, $414,000, and $10.6 million were recognized through earnings in the years ended December 31, 2011, 2010 and 2009, respectively, within total gain (loss) on investment securities, net.

Transfers of securities from available for sale to held to maturity are accounted for at fair value as of the date of the transfer. The difference between the fair value and the par value at the date of transfer is considered a premium or discount and is accounted for accordingly. Any unrealized gain or loss at the date of the transfer is reported in OCI, and is amortized over the remaining life of the security as an adjustment of yield in a manner consistent with the amortization of any premium or discount, and will offset or mitigate the effect on interest income of the amortization of the premium or discount for that held to maturity security.

Loans Held For Sale

Loans Held for Sale—Loans held for sale includes mortgage loans and are reported at the lower of cost or market value. Cost generally approximates market value, given the short duration of these assets. Gains or losses on the sale of loans that are held for sale are recognized at the time of the sale and determined by the difference between net sale proceeds and the net book value of the loans less the estimated fair value of any retained mortgage servicing rights.

Non-Covered Loans

Non-Covered Loans—Loans are stated at the amount of unpaid principal, net of unearned income and any deferred fees or costs. All discounts and premiums are recognized over the estimated life of the loan as yield adjustments. This estimated life is adjusted for prepayments.

Loans are classified as impaired when, based on current information and events, it is probable that the Bank will be unable to collect the scheduled payments of principal and interest when due, in accordance with the terms of the original loan agreement. The carrying value of impaired loans is based on the present value of expected future cash flows (discounted at each loan's effective interest rate) or, for collateral dependent loans, at fair value of the collateral, less selling costs. If the measurement of each impaired loans' value is less than the recorded investment in the loan, we recognize this impairment and adjust the carrying value of the loan to fair value through the allowance for loan and lease losses. This can be accomplished by charging-off the impaired portion of the loan or establishing a specific component to be provided for in the allowance for loan and lease losses.

Covered Loans

Covered Loans—Loans acquired in a FDIC-assisted acquisition that are subject to a loss-share agreement are referred to as "covered loans" and reported separately in our consolidated balance sheets. Covered loans are reported exclusive of the expected cash flow reimbursements expected from the FDIC. Acquired loans are aggregated into pools based on individually evaluated common risk characteristics and aggregate expected cash flows were estimated for each pool. A pool is accounted for as a single asset with a single interest rate, cumulative loss rate and cash flow expectation. The Company aggregated all of the loans acquired in the FDIC-assisted acquisitions into different pools based on common risk characteristics such as risk rating, underlying collateral, type of interest rate (fixed or adjustable), types of amortization, and other similar factors. A loan will be removed from a pool of loans only if the loan is sold, foreclosed, or assets are received in full satisfaction of the loan, and will be removed from the pool at its carrying value. If an individual loan is removed from a pool of loans, the difference between its relative carrying amount and its cash, fair value of the collateral, or other assets received will be recognized in income immediately as interest income on loans and would not affect the effective yield used to recognize the accretable yield on the remaining pool. Loans originally placed into a performing pool are not reported individually as 30-89 days past due, non-performing (90+ days past due or nonaccrual), or accounted for as a troubled debt restructuring as the pool is the unit of accounting. Rather, these metrics related to the underlying loans within a performing pool will be considered in our ongoing assessment and estimates of future cash flows. If, at acquisition, the loans are collateral dependent and acquired primarily for the rewards of ownership of the underlying collateral, or if cash flows expected to be collected cannot be reasonably estimated, accrual of income is inappropriate.

The cash flows expected to be received over the life of the pool were estimated by management with the assistance of a third party valuation specialist. These cash flows were input into a FASB ASC 310-30, Loans and Debt Securities Acquired with Deteriorated Credit Quality ("ASC 310-30") compliant loan accounting system which calculates the carrying values of the pools and underlying loans, book yields, effective interest income and impairment, if any, based on actual and projected events. Default rates, loss severity, and prepayment speeds assumptions will be periodically reassessed and updated within the accounting system to update our expectation of future cash flows. The excess of the cash flows expected to be collected over a pool's carrying value is considered to be the accretable yield and is recognized as interest income over the estimated life of the loan or pool using the effective yield method. The accretable yield may change due to changes in the timing and amounts of expected cash flows. Changes in the accretable yield are disclosed quarterly.

The excess of the undiscounted contractual balances due over the cash flows expected to be collected is considered to be the nonaccretable difference. The nonaccretable difference represents our estimate of the credit losses expected to occur and was considered in determining the fair value of the loans as of the acquisition date. Subsequent to the acquisition date, any increases in expected cash flows over those expected at purchase date in excess of fair value are adjusted through an increase to the accretable yield on a prospective basis. Any subsequent decreases in expected cash flows attributable to credit deterioration are recognized by recording a provision for covered loan losses.

The covered loans acquired are and will continue to be subject to the Company's internal and external credit review and monitoring. If credit deterioration is experienced subsequent to the initial acquisition fair value amount, such deterioration will be measured, and a provision for credit losses will be charged to earnings. These provisions will be mostly offset by an increase to the FDIC indemnification asset, and will be recognized in non-interest income.

The covered loan portfolio also includes revolving lines of credit with funded and unfunded commitments. Balances outstanding at the time of acquisition are accounted for under ASC 310-30. Any additional advances on these loans subsequent to the acquisition date are not accounted for under ASC 310-30.

FDIC Indemnification Asset

FDIC Indemnification Asset—The Company has elected to account for amounts receivable under the loss-share agreement as an indemnification asset in accordance with FASB ASC 805, Business Combinations. The FDIC indemnification asset is initially recorded at fair value, based on the discounted value of expected future cash flows under the loss-share agreement. The difference between the present value and the undiscounted cash flows the Company expects to collect from the FDIC will be accreted into non-interest income over the life of the FDIC indemnification asset.

Subsequent to initial recognition, the FDIC indemnification asset is reviewed quarterly and adjusted for any changes in expected cash flows based on recent performance and expectations for future performance of the covered portfolio. These adjustments are measured on the same basis as the related covered loans, at a pool level, and covered other real estate owned. Generally, any increases in cash flow of the covered assets over those previously expected will result in prospective increases in the loan pool yield and amortization of the FDIC indemnification asset. Any decreases in cash flow of the covered assets under those previously expected will trigger impairments on the underlying loan pools and will result in a corresponding gain of the FDIC indemnification asset. Increases and decreases to the FDIC indemnification asset are recorded as adjustments to non-interest income. The resulting carrying value of the indemnification asset represents the present value of amounts recoverable from the FDIC for future expected losses and the amounts due from the FDIC for claims related to covered losses.

Income Recognition On Non-Covered, Non-Accrual And Impaired Loans

Income Recognition on Non-Covered, Non-Accrual and Impaired Loans—Non-covered loans, including impaired non-covered loans, are classified as non-accrual if the collection of principal and interest is doubtful. Generally, this occurs when a non-covered loan is past due as to maturity or payment of principal or interest by 90 days or more, unless such non-covered loans are well-secured and in the process of collection. Generally, if a non-covered loan or portion thereof is partially charged-off, the non-covered loan is considered impaired and classified as non-accrual. Non-covered loans that are less than 90 days past due may also be classified as non-accrual if repayment in full of principal and/or interest is in doubt.

When a non-covered loan is classified as non-accrual, all uncollected accrued interest is reversed to interest income and the accrual of interest income is terminated. Generally, any cash payments are applied as a reduction of principal outstanding. In cases where the future collectability of the principal balance in full is expected, interest income may be recognized on a cash basis. A non-covered loan may be restored to accrual status when the borrower's financial condition improves so that full collection of future contractual payments is considered likely. For those non-covered loans placed on non-accrual status due to payment delinquency, this will generally not occur until the borrower demonstrates repayment ability over a period of not less than six months.

Non-covered loans are reported as restructured when the Bank grants a concession(s) to a borrower experiencing financial difficulties that it would not otherwise consider. Examples of such concessions include forgiveness of principal or accrued interest, extending the maturity date or providing a lower interest rate than would be normally available for a transaction of similar risk. As a result of these concessions, restructured loans are impaired as the Bank will not collect all amounts due, both principal and interest, in accordance with the terms of the original loan agreement. Impairment reserves on non-collateral dependent restructured loans are measured by comparing the present value of expected future cash flows on the restructured loans discounted at the interest rate of the original loan agreement to the loan's carrying value. These impairment reserves are recognized as a specific component to be provided for in the allowance for loan and lease losses.

The decision to classify a non-covered loan as impaired is made by the Bank's Allowance for Loan and Lease Losses ("ALLL") Committee. The ALLL Committee meets regularly to review the status of all problem and potential problem loans. If the ALLL Committee concludes a loan is impaired but recovery of the full principal and interest is expected, an impaired loan may remain on accrual status.

Allowance For Loan And Lease Losses

Allowance for Loan and Lease Losses—The Bank performs regular credit reviews of the loan and lease portfolio to determine the credit quality of the portfolio and the adherence to underwriting standards. When loans and leases are originated, they are assigned a risk rating that is reassessed periodically during the term of the loan through the credit review process. The Company's risk rating methodology assigns risk ratings ranging from 1 to 10, where a higher rating represents higher risk. The 10 risk rating categories are a primary factor in determining an appropriate amount for the allowance for loan and lease losses. The Bank has a management ALLL Committee, which is responsible for, among other things, regularly reviewing the ALLL methodology, including loss factors, and ensuring that it is designed and applied in accordance with generally accepted accounting principles. The ALLL Committee reviews and approves loans and leases recommended for impaired status. The ALLL Committee also approves removing loans and leases from impaired status. The Bank's Audit and Compliance Committee provides board oversight of the ALLL process and reviews and approves the ALLL methodology on a quarterly basis.

Each risk rating is assessed an inherent credit loss factor that determines the amount of the allowance for loan and lease losses provided for that group of loans and leases with similar risk rating. Credit loss factors may vary by region based on management's belief that there may ultimately be different credit loss rates experienced in each region.

Regular credit reviews of the portfolio also identify loans that are considered potentially impaired. Potentially impaired loans are referred to the ALLL Committee which reviews and approves designated loans as impaired. A loan is considered impaired when based on current information and events, we determine that we will probably not be able to collect all amounts due according to the loan contract, including scheduled interest payments. When we identify a loan as impaired, we measure the impairment using discounted cash flows, except when the sole remaining source of the repayment for the loan is the liquidation of the collateral. In these cases, we use the current fair value of the collateral, less selling costs, instead of discounted cash flows. If we determine that the value of the impaired loan is less than the recorded investment in the loan, we either recognize this impairment reserve as a specific component to be provided for in the allowance for loan and lease losses or charge-off the impaired balance on collateral dependent loans if it is determined that such amount represents a confirmed loss. The combination of the risk rating-based allowance component and the impairment reserve allowance component lead to an allocated allowance for loan and lease losses.

The Bank may also maintain an unallocated allowance amount to provide for other credit losses inherent in a loan and lease portfolio that may not have been contemplated in the credit loss factors. This unallocated amount generally comprises less than 10% of the allowance, but may be maintained at higher levels during times of economic conditions characterized by falling real estate values. The unallocated amount is reviewed periodically based on trends in credit losses, the results of credit reviews and overall economic trends.

As adjustments become necessary, they are reported in earnings in the periods in which they become known as a change in the provision for loan and lease losses and a corresponding charge to the allowance. Loans, or portions thereof, deemed uncollectible are charged to the allowance. Provisions for losses, and recoveries on loans previously charged-off, are added to the allowance.

The adequacy of the ALLL is monitored on a regular basis and is based on management's evaluation of numerous factors. These factors include the quality of the current loan portfolio; the trend in the loan portfolio's risk ratings; current economic conditions; loan concentrations; loan growth rates; past-due and non-performing trends; evaluation of specific loss estimates for all significant problem loans; historical charge-off and recovery experience; and other pertinent information.

Management believes that the ALLL was adequate as of December 31, 2011. There is, however, no assurance that future loan losses will not exceed the levels provided for in the ALLL and could possibly result in additional charges to the provision for loan and lease losses. In addition, bank regulatory authorities, as part of their periodic examination of the Bank, may require additional charges to the provision for loan and lease losses in future periods if warranted as a result of their review. Approximately 80% of our loan portfolio is secured by real estate, and a significant decline in real estate market values may require an increase in the allowance for loan and lease losses. The U.S. recession, the housing market downturn, and declining real estate values in our markets have negatively impacted aspects of our loan portfolio, and have led to an increase in non-performing loans, charge-offs, and the allowance for loan and lease losses. A continued deterioration or prolonged delay in economic recovery in our markets may adversely affect our loan portfolio and may lead to additional charges to the provision for loan and lease losses.

Reserve For Unfunded Commitments

Reserve for Unfunded Commitments—A reserve for unfunded commitments is maintained at a level that, in the opinion of management, is adequate to absorb probable losses associated with the Bank's commitment to lend funds under existing agreements such as letters or lines of credit. Management determines the adequacy of the reserve for unfunded commitments based upon reviews of individual credit facilities, current economic conditions, the risk characteristics of the various categories of commitments and other relevant factors. The reserve is based on estimates, and ultimate losses may vary from the current estimates. These estimates are evaluated on a regular basis and, as adjustments become necessary, they are reported in earnings in the periods in which they become known. Draws on unfunded commitments that are considered uncollectible at the time funds are advanced are charged to the allowance. Provisions for unfunded commitment losses, and recoveries on loans commitments previously charged-off, are added to the reserve for unfunded commitments, which is included in the Other Liabilities section of the consolidated balance sheets.

Loan Fees And Direct Loan Origination Costs

Loan Fees and Direct Loan Origination Costs—Loan origination and commitment fees and direct loan origination costs are deferred and recognized as an adjustment to the yield over the life of the related loans.

Restricted Equity Securities

Restricted Equity Securities—Restricted equity securities were $32.6 million and $34.5 million at December 31, 2011 and 2010, respectively. Federal Home Loan Bank stock amounted to $31.3 million and $33.2 million of the total restricted securities as of December 31, 2011 and 2010, respectively. Federal Home Loan Bank stock represents the Bank's investment in the Federal Home Loan Banks of Seattle and San Francisco ("FHLB") stock and is carried at par value, which reasonably approximates its fair value. Management periodically evaluates FHLB stock for other-than-temporary or permanent impairment. Management's determination of whether these investments are impaired is based on its assessment of the ultimate recoverability of cost rather than by recognizing temporary declines in value. The determination of whether a decline affects the ultimate recoverability of cost is influenced by criteria such as (1) the significance of any decline in net assets of the FHLB as compared to the capital stock amount for the FHLB and the length of time this situation has persisted, (2) commitments by the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB, (3) the impact of legislative and regulatory changes on institutions and, accordingly, the customer base of the FHLB, and (4) the liquidity position of the FHLB.

Moody's Investors Services rating of the FHLB of Seattle as Aaa was confirmed in August 2011, but a negative outlook was assigned as Moody's revised the rating outlook to negative for U.S. government debt and all issuers Moody's considers directly-linked to the U.S. government. Standard and Poors' rating is AA+, but it also issued a negative outlook with the action reflecting the downgrade of the long-term sovereign credit rating of the U.S. in 2011. Based on the above, the Company has determined there is not an other-than-temporary impairment on the FHLB stock investment as of December 31, 2011.

As a member of the FHLB system, the Bank is required to maintain a minimum level of investment in FHLB stock based on specific percentages of its outstanding mortgages, total assets, or FHLB advances. At December 31, 2011, the Bank's minimum required investment in FHLB stock was $10.5 million. The Bank may request redemption at par value of any stock in excess of the minimum required investment. Stock redemptions are at the discretion of the FHLB. The remaining restricted equity securities balance primarily represents an investment in Pacific Coast Bankers' Bancshares stock.

Premises And Equipment

Premises and Equipment—Premises and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is provided over the estimated useful life of equipment, generally three to ten years, on a straight-line or accelerated basis. Depreciation is provided over the estimated useful life of premises, up to 39 years, on a straight-line or accelerated basis. Generally, leasehold improvements are amortized over the life of the related lease, or the life of the related asset, whichever is shorter. Expenditures for major renovations and betterments of the Company's premises and equipment are capitalized.

Management reviews long-lived and intangible assets any time that a change in circumstance indicates that the carrying amount of these assets may not be recoverable. Recoverability of these assets is determined by comparing the carrying value of the asset to the forecasted undiscounted cash flows of the operation associated with the asset. If the evaluation of the forecasted cash flows indicates that the carrying value of the asset is not recoverable, the asset is written down to fair value.

Goodwill And Other Intangibles

Goodwill and Other Intangibles—Intangible assets are comprised of goodwill and other intangibles acquired in business combinations. Goodwill and intangible assets with indefinite useful lives are not amortized. Intangible assets with definite useful lives are amortized to their estimated residual values over their respective estimated useful lives, and also reviewed for impairment. Amortization of intangible assets is included in other non-interest expense in the Consolidated Statements of Operations.

The Company performs a goodwill impairment analysis on an annual basis as of December 31. Additionally, the Company performs a goodwill impairment evaluation on an interim basis when events or circumstances indicate impairment potentially exists. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others, a significant decline in our expected future cash flows; a sustained, significant decline in our stock price and market capitalization; a significant adverse change in legal factors or in the business climate; adverse action or assessment by a regulator; and unanticipated competition.

The goodwill impairment test involves a two-step process. The first step compares the fair value of a reporting unit to its carrying value. If the reporting unit's fair value is less than its carrying value, the Company would be required to proceed to the second step. In the second step the Company calculates the implied fair value of the reporting unit's goodwill. The implied fair value of goodwill is determined in the same manner as goodwill recognized in a business combination. The estimated fair value of the Company is allocated to all of the Company's assets and liabilities, including any unrecognized identifiable intangible assets, as if the Company had been acquired in a business combination and the estimated fair value of the reporting unit is the price paid to acquire it. The allocation process is performed only for purposes of determining the amount of goodwill impairment. No assets or liabilities are written up or down, nor are any additional unrecognized identifiable intangible assets recorded as a part of this process. Any excess of the estimated purchase price over the fair value of the reporting unit's net assets represents the implied fair value of goodwill. If the carrying amount of the goodwill is greater than the implied fair value of that goodwill, an impairment loss would be recognized as a charge to earnings in an amount equal to that excess.

Mortgage Servicing Rights ("MSR")

Mortgage Servicing Rights ("MSR")— The Company determines its classes of servicing assets based on the asset type being serviced along with the methods used to manage the risk inherent in the servicing assets, which includes the market inputs used to value the servicing assets. The Company measures its residential mortgage servicing assets at fair value and reports changes in fair value through earnings. Fair value adjustments that encompass market-driven valuation changes and the runoff in value that occurs from the passage of time, are each separately reported. Under the fair value method, the MSR is carried in the balance sheet at fair value and the changes in fair value are reported in earnings under the caption mortgage banking revenue in the period in which the change occurs.

Retained mortgage servicing rights are measured at fair value as of the date of sale. We use quoted market prices when available. Subsequent fair value measurements are determined using a discounted cash flow model. In order to determine the fair value of the MSR, the present value of expected future cash flows is estimated. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income. This model is periodically validated by an independent external model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Key assumptions used in measuring the fair value of MSR as of December 31 were as follows:

	2011			2010			2009
Constant prepayment rate		20.39	%		18.54	%		18.35	%
Discount rate		8.60	%		8.62	%		8.70	%
Weighted average life (years)		4.5			4.5			4.5

The expected life of the loan can vary from management's estimates due to prepayments by borrowers, especially when rates fall. Prepayments in excess of management's estimates would negatively impact the recorded value of the mortgage servicing rights. The value of the mortgage servicing rights is also dependent upon the discount rate used in the model, which we base on current market rates. Management reviews this rate on an ongoing basis based on current market rates. A significant increase in the discount rate would reduce the value of mortgage servicing rights.

SBA/USDA Loans Sales And Servicing

SBA/USDA Loans Sales and Servicing—The Bank, on a limited basis, sells or transfers loans, including the guaranteed portion of Small Business Administration ("SBA") and Department of Agriculture ("USDA") loans (with servicing retained) for cash proceeds equal to the principal amount of loans, as adjusted to yield interest to the investor based upon the current market rates. The Bank records an asset representing the right to service loans for others when it sells a loan and retains the servicing rights. The carrying value of loans is allocated between the loan and the servicing rights, based on their relative fair values. The fair value of servicing rights is estimated by discounting estimated future cash flows from servicing using discount rates that approximate current market rates and using estimated prepayment rates. The servicing rights are carried at the lower of cost or market and are amortized in proportion to, and over the period of, the estimated net servicing income, assuming prepayments.

For purposes of evaluating and measuring impairment, servicing rights are based on a discounted cash flow methodology, current prepayment speeds and market discount rates. Any impairment is measured as the amount by which the carrying value of servicing rights for a stratum exceeds its fair value. The carrying value of SBA/USDA servicing rights at December 31, 2011 and 2010 were $666,000 and $721,000, respectively. No impairment charges were recorded for the years ended December 31, 2011, 2010 or 2009 related to SBA/USDA servicing assets.

A premium over the adjusted carrying value is received upon the sale of the guaranteed portion of an SBA or USDA loan. The Bank's investment in an SBA or USDA loan is allocated among the sold and retained portions of the loan based on the relative fair value of each portion at the time of loan origination, adjusted for payments and other activities. Because the portion retained does not carry an SBA or USDA guarantee, part of the gain recognized on the sold portion of the loan may be deferred and amortized as a yield enhancement on the retained portion in order to obtain a market equivalent yield.

Non-Covered Other Real Estate Owned

Non-Covered Other Real Estate Owned—Non-covered other real estate owned ("non-covered OREO") represents real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property's new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for loan and lease losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Subsequent valuation adjustments are recognized within net loss on non-covered OREO. Revenue and expenses from operations and subsequent adjustments to the carrying amount of the property are included in other non-interest expense in the Consolidated Statements of Operations.

In some instances, the Bank may make loans to facilitate the sales of other real estate owned. Management reviews all sales for which it is the lending institution for compliance with sales treatment under provisions established within FASB ASC 360-20, Real Estate Sales. Any gains related to sales of other real estate owned may be deferred until the buyer has a sufficient initial and continuing investment in the property.

Covered Other Real Estate Owned

Covered Other Real Estate Owned—All OREO acquired in FDIC-assisted acquisitions that are subject to a FDIC loss-share agreement are referred to as "covered OREO" and reported separately in our statements of financial position. Covered OREO is reported exclusive of expected reimbursement cash flows from the FDIC. Foreclosed covered loan collateral is transferred into covered OREO at the collateral's net realizable value, less selling costs.

Covered OREO was initially recorded at its estimated fair value on the acquisition date based on similar market comparable valuations less estimated selling costs. Any subsequent valuation adjustments due to declines in fair value will be charged to non-interest expense, and will be mostly offset by non-interest income representing the corresponding increase to the FDIC indemnification asset for the offsetting loss reimbursement amount. Any recoveries of previous valuation adjustments will be credited to non-interest expense with a corresponding charge to non-interest income for the portion of the recovery that is due to the FDIC.

Income Taxes

 Income Taxes—Income taxes are accounted for using the asset and liability method. Under this method a deferred tax asset or liability is determined based on the enacted tax rates which will be in effect when the differences between the financial statement carrying amounts and tax basis of existing assets and liabilities are expected to be reported in the Company's income tax returns. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not, that all or some portion of the potential deferred tax asset will not be realized.

Derivative Loan Commitments

Derivative Loan Commitments—The Bank enters into forward delivery contracts to sell residential mortgage loans or mortgage-backed securities to broker/dealers at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage loan commitments. The commitments to originate mortgage loans held for sale and the related forward delivery contracts are considered derivatives. Effective in the second quarter of 2011, the Bank began executing interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting the interest rate swaps that the Bank executes with a third party, such that the Bank minimizes its net risk exposure. The Company recognizes all derivatives as either assets or liabilities in the balance sheet and requires measurement of those instruments at fair value through adjustments to accumulated other comprehensive income and/or current earnings, as appropriate. None of the Company's derivatives are designated as hedging instruments. Rather, they are accounted for as free-standing derivatives, or economic hedges, and the Company reports changes in fair values of its derivatives in current period net income.

The fair value of the derivative loan commitments is estimated using the present value of expected future cash flows. Assumptions used include pull-through rate assumption based on historical information, current mortgage interest rates, the stage of completion of the underlying application and underwriting process, the time remaining until the expiration of the derivative loan commitment, and the expected net future cash flows related to the associated servicing of the loan.

Operating Segments

Operating Segments—Public enterprises are required to report certain information about their operating segments in a complete set of financial statements to shareholders. They are also required to report certain enterprise-wide information about the Company's products and services, its activities in different geographic areas, and its reliance on major customers. The basis for determining the Company's operating segments is the manner in which management operates the business. Management has identified three primary business segments, Community Banking, Mortgage Banking, and Wealth Management. Prior to January 1, 2011, the Company reported Retail Brokerage, consisting of Umpqua Investments, as its own segment. Effective in 2011, the Company began reporting Umpqua Investments, Umpqua Private Bank, and Umpqua Financial Advisors under the Wealth Management segment. Umpqua Private Bank and Umpqua Financial Advisors do not meet the quantitative thresholds for reporting as separate segments and service the same customer base on Umpqua Investments.

Share Based Payment

Share-Based Payment—The Company has two active stock-based compensation plans that provide for the granting of stock options and restricted stock to eligible employees and directors. In accordance with FASB ASC 718, Stock Compensation, we recognize in the income statement the grant-date fair value of stock options and other equity-based forms of compensation issued to employees over the employees' requisite service period (generally the vesting period). The requisite service period may be subject to performance conditions.

The Company's 2003 Stock Incentive Plan provides for granting of stock options and restricted stock awards. Stock options and restricted stock awards generally vest ratably over 5 years and are recognized as expense over that same period of time.

The fair value of each option grant is estimated as of the grant date using the Black-Scholes option-pricing model using assumptions noted in the following table. Expected volatility is based on the historical volatility of the price of the Company's common stock. The Company uses historical data to estimate option exercise and stock option forfeiture rates within the valuation model. The expected term of options granted is determined based on historical experience with similar options, giving consideration to the contractual terms and vesting schedules, and represents the period of time that options granted are expected to be outstanding. The expected dividend yield is based on dividend trends and the market value of the Company's common stock at the time of grant. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant corresponding to the estimated expected term of the options granted. The following weighted average assumptions were used to determine the fair value of stock option grants as of the grant date to determine compensation cost for the years ended December 31, 2011, 2010 and 2009:

	2011			2010			2009
Dividend yield		2.79	%		2.72	%		2.23	%
Expected life (years)		7.1			7.1			7.3
Expected volatility		52	%		52	%		46	%
Risk-free rate		2.71	%		2.69	%		2.18	%
Weighted average grant date fair value of options granted	$	4.65		$	5.24		$	3.65

The Company's 2007 Long Term Incentive Plan provides for granting of restricted stock units for the benefit of certain executive officers. Restricted stock unit grants are subject to performance-based vesting as well as other approved vesting conditions. The current restricted stock units outstanding cliff vest after three years based on performance and service conditions. Compensation expense is recognized over the service period to the extent restricted stock units are expected to vest.

Earnings Per Share

Earnings per Share—According to the provisions of FASB ASC 260, Earnings Per Share, nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are participating securities and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines earnings per share for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company's nonvested restricted stock awards qualify as participating securities.

Net income, less any preferred dividends accumulated for the period (whether or not declared), is allocated between the common stock and participating securities pursuant to the two-class method, based on their rights to receive dividends, participate in earnings or absorb losses. Basic earnings per common share is computed by dividing net earnings available to common shareholders by the weighted average number of common shares outstanding during the period, excluding participating nonvested restricted shares.

Diluted earnings per common share is computed in a similar manner, except that first the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares, excluding the participating securities, were issued using the treasury stock method. For all periods presented, warrants, stock options, certain restricted stock awards and restricted stock units are the only potentially dilutive non-participating instruments issued by the Company. Next, we determine and include in diluted earnings per common share calculation the more dilutive effect of the participating securities using the treasury stock method or the two-class method. Undistributed losses are not allocated to the nonvested share-based payment awards (the participating securities) under the two-class method as the holders are not contractually obligated to share in the losses of the Company.

Advertising Expenses

Advertising expenses—Advertising costs are generally expensed as incurred.

Fair Value Measurements

Fair Value Measurements—FASB ASC 820, Fair Value Measurements and Disclosure, ("ASC 820", defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level hierarchy for disclosure of assets and liabilities recorded at fair value. The classification of assets and liabilities within the hierarchy is based on whether the inputs to the valuation methodology used for measurement are observable or unobservable. Observable inputs reflect market-derived or market-based information obtained from independent sources, while unobservable inputs reflect our estimates about market data. In general, fair values determined by Level 1 inputs utilize quoted prices for identical assets or liabilities traded in active markets that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement in its entirety falls has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability.

Reclassifications

Reclassifications—Certain amounts reported in prior years' financial statements have been reclassified to conform to the current presentation. The results of the reclassifications are not considered material and have no effect on previously reported net earnings (losses) available to common shareholders and earnings (losses) per common share.
